LETTER FOR ELECTRIC SIGNS.

Specification of Letters Patent.

Application filed July 3,1905. Serial No- 268g2'77.

'1'0 all who??? it Til/(1y concern:

Be it known that l, HoRAoEB. CAMP, a citizen of theUnited States, residing. at Akrun, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in-L'etters for Electric Signs, of which the following is a specification.

This invention relates to improvements in letters for electric signs; and the object is to provide a sim le construction of letter which may readily e attached to the sup ortingboard or other part and in which t' trical connections and Wiring are eiteotually insulatedand protected from the weather and from contact with the supporting-board or adjacent woodwork.

With the above object in view the inven tion consists in the novel features of construc tion hereinafter fully described, particularly 2o pointed out in the claims, and clearly illustrated in the accompanying drawings, in which 7 Figure 1 is a top plan view of a letter constructed in accordance with my invention;

2; Fig. 2, a sectional view taken on the line a a of Fig. 1 Fig. 3, a sectional view taken on the line b b of Fig. 1; Fig. 4, a plan view of under side of letter; Fig. 5, a sectional view upon the line 0 c of Fig. 4.

0 Referring, now more articularly to the drawings, 1 designates t ebody portion of the letter, which consists of an integral piece of earthenware formed in any desired style.

The body portion 1 is formed upon its top 3 5 with a channel or recess 2 and upon its under side with a similar channel 3, said channels 2 and 3 being separated by a wall or partition 4. Formed integral with the wall 4 are a se ries of depending sockets 5. These sockets 5 are constructed and arranged to receive the socket end of the ordinary incandescent electric lamp, the bottom of said sockets being formed to accommodate the screws and contact-plates for conducting the electric fluid 4 5- from the main-line wires through the lamps, as illustrated. The side Walls 6 of the chan nel or recess 3 project beyond the bottom of 'the sockets 5, so that said sockets are disposed wholly within the recess 3; The sockets 5 are provided at their up er ends with circular beads or ridges 7, whic serve to prevent any moisture which may collect in said recess 2 from runnin thereinto, and thus comeinto' contact wit the Wiring and electrioal connections of the lamp. After the vals with pairs of lugs Sfdisposed one upon 6 e elec- ,in'devices of this character. all wiring and electrical connections are comlamps have been inserted into the sockets 5 and connected with the main-line wires in the usual manner the channel or recess); is filled with a suitable plastic insulating (OlllPOSl tion, thus completely covering the sockets 5, co the wiring, and electrical connections.

In order to attach the letterto the supporting-board or other part, 1 provide the side walls of the channel 3 at suitable intereach of said walls and spaced from the wall 4. Upon the top of these lugs, between the same and the wall 4, a plate 9 is positioned, which is provided with an opening to admit the passage of a bolt, the head of said bolt lying in the space between the plate and the bottom of the channel. When the channel is filled with the plastic material, as above described, the bolt is held firmly in position. with its shank portion extending outwardly therefrom, by means of which the letter may be readily attached to the desired part.

By forming the sockets wholly within the channel or recess 3 'a flat surface is presented to the supporting-board or other part, thus obviating the boring of holes to receive the socket, which has been necessary heretofore Furthermore,

pletely covered and thus protected from the Weather and kept out of contact with the adjacent woodwork,- whereby all danger from fire in consequence of defective insulation is eiiectually obviated. V

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent of the United States, is-

1., A letter for signs comprising a body portion provided on its top and under sides with recesses, and depending sockets tor the 5 reception of incandescent lamps formed hi tegral therewith, and disposed witlun the channel on the under side thereof.

2. A letter for electric signs comprising a body portion formed. with a recess therein and provided with depending sockets for thr rect ption of electric lamps, said sockpts bein provided at their upper end with a cirr-ul n bead-ring projecting beyond the bottom wall of said recess.

3. A letter for signs comprising a body portion provided upon its top and under sides with recesses, sockets extending upon the under side of the body portion and disposed within one of said channels, and beadno body portion formed with a channel upon its under side, depending sockets carried thereby, lugs carrie by the side wall of said channeldisposed in pairs, a plate lying across said lugs and provided with a perforation to receive the shank portion of a bolt and a bolt passing through the perforation with its head positioned between said late and the bottom of the channel and a apted to be held in position by means of suitable filling material.

5. A letter for electric signs com rising a body portion formed on its under si e with a recess, and de ending socketsformed integral with sai body portion and disposed within said channel.

6. A letter for electric signs comprisin a body portion formed on its under side wit a In testimony whereof I aflix my signature in presence of two witnesses.
